Reenable feature policy control over fullscreen

This CL also changes test expectations to bring the fullscreen tests in
line with the new behaviour prescribed by Feature Policy.

Specifically:
 - Same origin iframes by default have the same ability to use
   fullscreen as their parent frame. Tests which previously only used
   same-origin frame have been changed to verify the new behaviour,
   and new tests in LayoutTests/http/tests have been added to test the
   same situation with cross-origin frames.
 - Dynamic modification of the allowfullscreen flag has no effect until
   the iframe contents are navigated/reloaded.
 - Web platform tests are marked as failing, and should remain so until
   the fullscreen spec is updated fo include the new behaviour.
 - A new Browser test class is created which explicitly disables
   feature policy so that we don't lose coverage for the old behaviour
   when FP is disabled.
